PREFACE. 
——ae—— 
Tuts third volume contains the Orders of CALYCIFLOR with a 
monopetalous corolla and an inferior ovary. The fourth volume 
(shortly to be in preparation for press) will, it is hoped, include 
the Heaths (Hricee) and all the Monopetale with superior 
ovaries, 4. €. the COROLLIFLOR& proper. The fifth volume will 
probably take in all the MonocHLAMYDE, and the sixth the 
- Mownocotyieponss and Ferns, completing the work. 
At this stage of their publication the authors feel themselves 
unwillingly compelled to fix the price of the present and future 
volumes at eighteen shillings, instead of selling them at twelve 
_ shillings, as charged for Vols. I. and IJ. Those volumes, having 
been published at the lower price, will continue to be sold at it. 
The advance is only to be charged on Vols. IIT, IV., V., VI. 
This measure has become necessary in self defence, owing to the 
price of the earlier volumes having been fixed much too low; 
for, after paying expenses and allowing for interest of money, 
_ although a considerable part of the edition has been sold, the 
_ profits are still in expectancy. Nor do they anticipate that the 
“3 purchasers of this work, on reflection, will consider the price 
___—heaeeforward to be charged as unreasonably high. On the con- 
ont: it will be found rather wnder than over that charged for 
similar works. The Australian Flora of Mr. Bentham, a work 
on a similar plan, and one that will include fully as many volumes, 
sells at twenty shillings per volume, and no one complains that 
this price is excessive. The volumes of the Cape Flora are of 
equal size, and equally closely printed. Both works stand on a 
somewhat similar footing, namely, that they enjoy government 
grants of £150 each volume, in aid of publication.
